Date: Mon, 30 May 2016 13:49:34 -0700 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Adrian Hunter <adrian.hunter@...el.com>, Ulf Hansson <ulf.hansson@...aro.org> Subject: [PATCH 4.5 36/87] mmc: sdhci-pci: Remove MMC_CAP_BUS_WIDTH_TEST for Intel controllers 4.5-stable review patch. If anyone has any objections, please let me know. ------------------ From: Adrian Hunter <adrian.hunter@...el.com> commit 822969369482166050c5b2f7013501505e025c39 upstream. The CMD19/CMD14 bus width test has been found to be unreliable in some cases. It is not essential, so simply remove it.
